Generally speaking, the temperature of printing workshop about 20~22℃, the humidity about 45~60RH%. At present, most of printing factory has a good humidity control in China. And also has special requirement for paper storage, about 18~20℃, 60~65RH% to keep paper moisture before printing.
The best humidification:
1. Ultrasonic industrial hummidifier.
2. Electrode humidifying.
3. wet membrane humidifier.
4. Micro-mist humidifier.

static electricity phenomena

1. In the process of printing production, sometimes paper or printed matter to attract each other together, it is difficult to separate, this picture is printed electrostatic phenomenon.
2. Static electricity phenomena are taken as factors among numerous influencing factors.
3. Static electricity phenomena can comes out Electrostatic printing ink.
4. Static electricity causes air discharge, and cause electric shock or fire.

Humidification for printing industrial
1. For paper moisture, paper deformation, Paper edge uneven.
2. Paper shrinkage deformation in stampling.
4. ink viscosity and printing operation

Fabric printing
If low humidity, it will effect equipment and quality.
